Description

The LM8207 is a combination of 18-channel gamma buffers, a VCOMdriver and a temperature compensated internal voltage reference. It is designed for buffering voltage levels and driving high capacitive loads in large TFT panels. The gamma buffers are individually optimized to the input/output requirements of their respective gamma position to cover the whole voltage range from rail to rail. Any desired gamma correction curve can be obtained by combining the gamma buffers with external resistors. The VCOMdriver has a high output current capability and is stable with large capacitive loads, typical for large panel sizes. This will result in a fast recovery time for large voltage variations at the output. The internal band gap reference can be used to form a highly stable voltage to generate the gamma correction voltages. In combination with the internal amplifier, the reference voltage can be programmed to voltages up to the positive rail. The LM8207 is offered in a 48-pin TSSOP package.
